Abstract

Objective: To compare the post-operative complication rate in Transcatheter Aortic Valve Implantation [TAVI] vs Surgical Aortic Valve Replacement [SAVR] within one week of the operation.
Methods: This is a retrospective cohort study in which two separate cohorts of patients would be included. The first group is of patients who undergo traditional open-heart surgery at our hospital for valve replacement, whereas the other cohort would be of patients who undergo valve replacement procedure using TAVI. Records of all the patients who underwent TAVI and SAVI in the last 5 years preceding the survey and fulfilling our inclusion criteria would be included in our study using purposive sampling method until the desired sample size is achieved. The inclusion criteria include patients who underwent primary valve replacement surgery at our institute through either of these procedures, patients who remained admitted in the hospital for at least one week and whose medical records are readily available at the hospital.
Results: A higher Postoperative Complication Rate observed with SAVR compared with TAVI. The Myocardial Infarction, Acute kidney failure and Stroke reported higher after SAVR compared to TAVI.
Conclusion: TAVI is a safer and more reliable procedure for Patients suffering from Aortic Stenosis
